makananu ya gagana ing check valve
Ingcheck valve magagamit ya keng pipeline system, at ing peka-obra na yapin ing pigilan ing pamagbalik ning medium, ing pamag-reverse rotation ning pump ampo ing kayang driving motor, ampo ing pamag-discharge ning medium keng container.
lawan la reng balbula malyari ya namang gamitan kareng linya a magsuplay kareng auxiliary system nung nukarin ing pressure malyari yang mitas babo ning pressure ning main system. Deng check valves malyari lang gamitan kareng pipeline da reng miyayaliwang media agpang kareng miyayaliwang materyales.
Ing check valve maka-install ya keng pipeline at maging metung ya kareng fluid components ning kumpletung pipeline. Ing pamagbukas ampo pamagsara ning valve disc apektadu ya keng transient flow state ning sistema nung nukarin ya atyu; ing pamagsara nang katangian ning valve disc atin yang epektu keng fluid flow state.
Check valve classification
Ing disc ning swing check valve atin yang pormang disc ampo mag rotate ya keng shaft ning valve seat channel. Uling ing channel keng valve streamlined ya, ing flow resistance mas malati ya kesa keng lift check valve. Iti masanting ya para kareng mababang danum ampo e maralas a pamagbayu keng danum. Makanyan man, ali ya masanting para keng pulsating flow, ampo ing kayang sealing performance ali ya kasing galing ning lifting type.
Ing swing check valve makadake ya keng atlung uri: single-lobe type, double-lobe type ampo multi-lobe type. Deting atlung porma keraklan makadake la agpang keng diametru ning balbula.
2. Iangat me ing check valve
Metung a check valve nung nukarin ing valve disc mag slide ya keng vertical centerline ning valve body. Ing lift check valve malyari ya mung i-install keng horizontal pipeline, ampo ing bola malyari yang gamitan para keng valve disc keng high-pressure small-diameter check valve. Ing valve body shape ning lift check valve parehu ya keng globe valve (malyari yang gamitan keng globe valve), inya mas maragul ya ing fluid resistance coefficient na. Kalupa ne ning globe valve ing kayang istruktura, at pareu la king globe valve ing katawan ning balbula ampong disc.
Metung a check valve nung nukarin ing disc mag rotate ya keng pin keng luklukan. Ing disc check valve atin yang simpleng istruktura at malyari ya mung i-install keng horizontal pipeline, ampo ing pamag-seal performance e ya masanting.
4. Pipeline check valve
Metung a balbula nung nukarin ing disc mag slide ya keng libutad ning katawan ning balbula. Ing pipeline check valve metung yang bayung valve. Malati ya sukad, magaan ya at masanting ya keng pamagprosesu. Metung ya kareng direksyun ning panyulung ning check valve. Makanyan man, ing fluid resistance coefficient mas maragul ya kesa keng swing check valve.
5. Compression check valve
Ing klasing balbula ayni magagamit ya bilang boiler feed water ampo steam cut-off valve, atin yang integrated function a lift check valve ampo globe valve o angle valve.
Dagdag pa, atin muring check valves na e masanting para keng pump outlet install, antimo ing foot valve, spring type, Y type, atbp.
